Aaron C. Bought: Galaxy S21 Ultra 5G AT&T 5 months ago

To start with I had trust issues about the whole thing. When I saw the price I even thought that the phone could be an imitation. I also expected the phone to have issues, like a borken screen or chipped frame. I did not expect the product to be in such good condition. For the most part, refurbished...

There were some pieces of information that belonged to the refurbisher, and should have been wiped for the ...

I love this unlocked phone and the process for buying it was seamless. I bought it refurbished but it was actually a NEW phone complete with its original packaging. However, my first purchase of this phone (refurbished) was advertised as unlocked (but was locked), so that didn't go so well. I inves...
